PRESS-FITTING PIPE JOINT METHOD AND PRESS-FITTING PIPE CAULKING DEVICE FOR USE IN THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a press-fitting pipe joint method in which press-fitting pipes mutually connected by screw fastening through a joint can be fixed simply and reliably without looseness at low cost, to the press-fitting pipes constituting press-fitting pipe piles press-fitted into the ground as foundation piles, and provide a press-fitting pipe caulking device for use in the method.;SOLUTION: A press-fitting pipe joint method is configured by mutually connecting adjacent steel pipes 2, 2 by screw fastening in the shaft AX direction through a joint 30, the steel pipe piles press-fitted and driven into the ground. The joint 30 has a male screw part 32 and a through-hole 31 penetrating in the wall thickness t direction. An open end 11 side of one first steel pipe 10 among the steel pipes 2 is formed of female screw parts 12 screwed with male screw parts 32 and a deformation part 13 for applying a pressing force F. After the female screw part 12 of the first steel pipe 10 are fastened with the male screw parts 32 of the joint 30, the deformation part 13 of the first steel pipe 10 is caulked in the through-hole 31 of the joint 30 from the outside, and the detent between the male screw part 32 and the female screw part 12 is performed.;COPYRIGHT: (C)2015,JPO&INPIT
